BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 669,386, dated March 5,1901.

l Application flied Aprn4,19oo. serai No. 11,469. (Numan.)

To .all whom, t may concern:

Be it known that I, CALVIN FoRBUsH, a citizen of the United States,residing at New York, (Richmond Hill,) in the county of Queens and Stateof New York, have invented a new and useful Bottle-Stopper, of which thefollowing is a specification.

My invention relates to Stoppers for bottles, and has for its object toproduce a simple and eicient device which will be very effective insealing the bottle, which can be applied quickly and easily, and whichcan be removed without the use of a tool. I attain this object by themechanism illustrated in the accompanying drawings, in which- Figure 1is a view of a bottle with my improved bottle-stopper applied thereto.Fig. 2 is a central longitudinal section through the neck of the bottleand stopper, taken at right angles to Fig. 1; and Fig. 3 is a bottomplan view of the clamping-cap.

In the accompanying drawings like parts are indicated by the samenumerals of reference in each of the views, and in the praetice of myinvention I provide a metal cap 5,

proportioned in size to fit snugly on the top of the bottle 6, andwithin the cap 5 I mount a cork or elastic packing 8, which is the samein diameter as the interior of the said cap or a trifle greater indiameter, so as to t tightly within said cap. `I also provide aclampingplate 9, which is provided with a lug 10, which may be integraltherewith or may be secured thereto, and through which is passed thebail 11 of a clamp 12 of any desired construction, preferably theWell-known construction shown in the drawings, and by means of which itis held in place, as will be readily understood, and the under side ofthe clamping-plate 9 has a central convex portion 13, as clearly shownin Figs. 2 and 3.

In operation, the bottle being irst filled, the cap 5 is placedinposition on the bottle, so that the cork or elastic packing-plate 8 willrest over the mouth of the bottle. The clamping-plate 9 is then placedupon the top of the cap 5 and is drawn down upon the same by theclamping device 12, and this clamping device is so proportioned in size,as well as the convex part 13 of the clamping-plate 9, that the saidconvex part will depress the central part of the cap 5 and packing-plate8 and force the central part of said packingplate 8 below the plane ofthe mouth of the bottle, as clearly shown in Fig. 2, while the rim ofthe clamping plate or cap 9 will force the packing-plate into closecontact with the edge or rim of the bottle surrounding the mouth, as isalso clearly shown in said figure, and a veryT tight seal will be theresult. It will thus be seen that by this construction I am able toprovide a bottle-stopper which can be secured in place and removedwithout the use of an instrument of any kind. With it I can make a verytight seal, and the stopper can be used a large number of times withoutthe deterioration to any appreciable extent of any part except thepacking-plate 8, which can be easily and inexpensively renewed.

I do not confine myself to the material used nor to the extension of thecap 5 down over the neck of the bottle nor to the formation of the lug10, but reserve the right to make all changes which fairly come withinthe scope of my invention.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a bottle-stopper, a cap, a packingplate mounted therein, aclamping plate mounted thereon, said clamping-plate being provided witha convex under surface, and means to clamp said clamping-plate upon saidcap, as and for the purpose set forth.

2. A bottle-stopper, comprising a cap, a packing-plate mounted therein,a clampingplate mounted thereon, and provided with a lug having anaperture therethrough, and a clamping device, as 12, having a bailadapted to pass through said apertured lug, as and for the purpose setforth.

In testimony whereof I have signed my name to this specification in thepresence ofv two subscribing witnesses.

CALVIN FORBUSH.
